- LI'ICHFIELD, CONNECTICUT, A CORPORATION OF DELAWARE SWITCH HANDLE ATTAOHIN G MEANS Application filed January 22,1929. Serial No. 334,301.

The invention relates to handles for elec trical switches and is designed primarily for use with switches of the encased type, and it is the principal object of the invention to provide new and improved means for connecting the handle with a member to be operated thereby, the construction being such that said handle may be shipped within the switch casing and easily applied when the switch is in stalled. It is to be understood however that the invention is not restricted to use with encased switches even though this is the primary intent. I

With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Figure 1 is a side elevation showing the handle secured in switch-open position.

Fig. 2 is a View similar to Fig. 1 but showing the handle secured in switch-closed posi tion.

Fig. 3 is an elevation looking in the direction indicated by the arrow A of Fig. 1.

Fig. 4 is a similar view as indicated by arrow B of Fig. 2.

Fig. 5 is a vertical sectional view on line 55 of Fig. 1.

Fig. 6 is a disassembled perspective view of a number of closely related parts.

In the drawings above briefly described, C denotes a switch casing which may contain any desired form of switch and operating means for said switch. A squared shaft S is shown projecting outwardly through an opening 0 in the casing, and the handle serves to turn this shaft in one direction or the other as occasion may demand.

A metal plate 7 is shown provided with a socket 8 which receives the outer end of the shaft S, said plate being secured upon said shaft by a central screw N. In this or some other adequate way, plate 7 is connected to shaft S to effect turning of the latter when said plate is turned. At opposite points, lugs 9 and 10 are shown extending laterally in the same direction from the peripheral portion of the plate 7 the outer ends 9a-10a of said lugs being bent inwardly toward each other and having openings 96-106 respectively.

at its outer end with an insulating hand-grip 12 which is preferably in the form of a ball threaded upon said handle end. The other end portion of the handle 11 is by preference flattened as indicated at 13 and the outer extremity of this flattened portion is offset, providing a transverse shoulder 14 for reception in the slot 9?) when the handle is rocked in the proper direction. When this shoulder 14 is completely received in the slot 96, it abuts the walls of this slot, the flattened portion 13 at one side of said shoulder lies against the outer sides of the lug ends 9a10a, and the inner handle extremity 15 lies against the inner side of the lug end 9a. The handle is thus connected with the plate 7 in such a manner that it may be removed from this plate only by outward swinging, and to prevent such swinging, a bolt 16 is employed. This bolt passes through an opening 17 in the flat handle portion 13 and through the opening 10b of the lug end 10a. A look washer 18 is preferably provided for the nut 19 of the bolt 16, and as a further precaution against accidental loosening of the handle, a cutter pin 20 preferably passes through the free end of said bolt.

In practice, the handle 11 with the parts 1819-20 connected with it, is packed within the casing C and hence there is 1710Z1, and the parts 18-l920 are applied. he handle is thus rigidly connected with the plate 7 to serve as turning means for the latter to effect either opening or closing of the switch. Should it be desired at any time to prevent unauthorized persons no danger of bending the handle in rough 1 a slot 22 for registration with similar slots in either of twostationary lugs 23-24 car- 'ried by-thecasing-C, said lugs- 23-2t being 7 preferably integral with an annular plate 25 riveted orotherwise secured to said casing around the shaft S. A padlockz26tis shownv for locking lug 21 to either of the lugs 23-24,

handle against such swlngmg.

allowing the switch *to be'looked either in it open or closed ,positions.

' Not only 1s the construction herein disc'losed ofeXcepti'onally simple and inexpensive nature, but it iseiiicient, reliable and ad- Wantageous "from numerous standpoints, For these reasons, the details which havebeen illustrated'are preferably followed. However,'within' the scope of the invention as claimed, variations maybe -made.'

1. In :a switch operating means, a member for connection with a switch-throwingpart, said member having a lug formed with an opening, a handle having an offset end pro viding it with a transverse shoulder, said shoulder passing through and abutting the walls of said slot, and the handle portions at opposite sides of said shoulder being disposed against opposite sides of said lug, whereby the o'fli'set handle .end 'oan'be removed from the lug only by swingingo f the handle, and meansspiaced from said offset end and securing the handle to the aforesaid member to prevent such swinging of the handle.

2. In a'swit'ch operating means, a member for connection ,witha switch-throwing part, said memberhaving'two' spaced laterally pro- ,iecfting lugs each formed withan opening, a handle having an end receivable ,inthe openingot one of said lugs, and a fastener en- I gaged with the handle and receivablein v the opening of the other lug torsecuring said handle againstdisengagement from'the opening of said one lug.

3. In a switc'hoperating means, a plate for connection witha switch-throwing part, said plate having two opposed peripheral lugs both projecting "laterally from one of its-sides, the outer ends of said lugs being bent inwardly toward each' other, a handle lyingagainst the outer sides of said inwardly bent lug ends, and means securing saidhandle to sa d lug ends.

4. In a swltch operatingmeans, a plate for connection with a switch-throwing part, said plate having two opposed peripheral lugs both projecting laterally from one of its sides,
